Abstract
US Federal Regulations require at least two pivotal proofs of efficacy clinical trials (typically Phase III) to support approval of a drug for a specific indication. In the clinical development of drugs to treat panic disorder, one of these trials may incorporate a forced titration design while the other may incorporate a flexible titration - according to response design. Standard analysis approaches include treatment group comparisons at each follow-up visit in terms of variables reflecting domains of the panic condition. Such designs pose challenges as to: (1) characterizing the dose response profile across both studies; {2) characterizing duration of effect; (3) characterizing withdrawal effects; and (4) the choice of appropriate statistical analysis methods. Standard approaches to meeting these challenges, as well as reasonable alternatives are presented.
